6.2 Expansion vessel module
The STREBEL Q25S and Q38S boilers can be provided with an expansion vessel
module. By this means the external expansion vessel is not required. This expansion
vessel module is placed behind the STREBEL S-HQ boiler, by which means the
expansion vessel is not noticeable. The content of the two expansion vessels is 20 litres.
The pre-charge pressure is 1 bar.
The expansion vessel module can be supplied with the necessary pipes to connect with
the STREBEL S-HQ boiler. The connecting pipes for the installation correspond with
those of the boiler and have the same centre-to-centre distance to the wall.
When checking the expansion vessels these are accessible via the left, right and upper
sides. From these sides the tanks are also removable and the boiler does not have to
be dismantled.
The space which is required for mounting the expansion vessel module corresponds
with the required space for mounting an STREBEL S-HQ boiler. They included template
and mounting strip for the boiler which can be used for the expansion vessel module.
The boiler is fitted on to this after the expansion vessel module has been mounted. The
necessary mounting strip for the boiler is present on the module.
